Hey Jerry, I'm sorry it's not so much that the end cap is moving it's the bearing inside that seems like it has play, up and down between the end cap and the crank. I'm guessing 1/16 but it could be less. The engine ran very smoothly (no strange noises or such) before I took the oil pan off. I'm wondering if there is supposed to be a slight gap for oil or? I'll try and get some close up pics soon.
